even if that's all true, it doesn't change the fact that there are typically good entry/exit points.
This run-up appears to be a great one. Now I haven't put my money where my mouth is....but I won't be shocked to see BTC down 20%+ over the next couple months.
It'll definitely have down turns. If you're good at day/frequent trading, go for it. 98% of people aren't able to predict the price action well enough to beat dollar cost averaging with Bitcoin, especially on frequent trading and with the tax consequences. But, if you can, go for it!
But if one has to ask a message board whether or not they should sell their Bitcoin, I think it's pretty likely that they'll wind up losing money.
